Canon 80D replacement

[DD_Crash]

As my kit is a little heavy I am going to get a replacement. I have been to a couple of shops to trade my kit in and the choice seems to be a Canon R10(new) + kit lens or Lumix G9 and some used lenses I am not sure what the best value would be My present lens are
Canon 24-105L
Canon 70-300L
Sigma 10-20
Canon 50 1.8
Kenko 1.4 extender

Thanks Pooh, I have decided to go M43 either Lumix G9 or Oly Em1 mk3 due to the weight of the lenses
